A.R.Rahman has been quite active on Facebook for some time now interacting with his fans. During one such interaction, the Mozart of Madras replied to an interesting question, with a lighthearted finish.
Fan's question: Sir, May I know who is that female voice in Tango Kelaiyo (Kaatru Veliyidai) song?
Rahman's reply: "Dear Fazil, Thank you for your kind words. Its Haricharan himself with his vocal formant and pitch tweaked to modulate like a young sensuous female..we tried others but we couldn’t get this quality so retained the temp..
Ps - just finished the 'Cheliyaa' press meet at Hyderabad and sitting jobless now ;-)"
That's quite interesting!
